“…In all mound age classes bryophytes had significantly higher mean numbers of species than vascular plants (Table 5). These results are consistent with the findings of Jonsson and Esseen (1998) and Heinken and Zippel (2004) in coniferous forests of the boreal and temperate zone, where bryophytes create dense carpets on the forest floor. Rapid response of bryophytes to gaps in the closed layer of cryptogams had been attributed to their high abundance on the forest floor, a great variety of regeneration strategies and large numbers of propagules.…”

“…In bryophytes, diaspores include not only spores and specialized asexual propagules, but also detached stems or buried old stem fragments (During 1997). Heinken and Zippel (2004) showed that in addition to clonal ingrowth from the edge, detached and fragmented stems played an important role in the re-colonization of experimentally disturbed plots. Frego (1996) observed detached or fragmented stems within several metres of their origin.…”

“…Methods of vegetative reproduction are undoubtedly of utmost importance for population development and maintenance as well as population spread in many bryophyte taxa (e.g., Correns 1899; Longton and Schuster 1983;During 1990;Heinken and Zippel 2004). For R. rugosum, three different structures of vegetative reproduction s.l.…”

“…Generally, vegetative diaspores can be dispersed over small to medium distances (but see above for clonal diaspores) through running water (hydrochory), wind (anemochory), and animal activities (epizoochory, dysochory) (compare, e.g., Heinken et al 2001;Heinken and Zippel 2004). Such dispersal events of vegetative R. rugosum diaspores are demonstrated in the studied plots: HB1_43_1 is the sole sample from HB1 assigned to HB_clone3 otherwise only detected in HB2, thus indicating successful dispersal and establishment (genet extension ≥25 m).…”

“…The formation of, e.g., dendroids, turfs, mats, wefts, and tails leading to distinct patches is a well-known and characteristic feature of many taxa. Clonal reproduction probably occurs in many of these taxa, especially in pleurocarpous mosses, mainly through gradual decay and disintegration of older shoot parts, thus separating the younger shoots (Correns 1899;Longton and Schuster 1983;During 1990;Heinken and Zippel 2004).…”

Vegetative reproduction and clonal diversity in Rhytidium rugosum (Rhytidiaceae, Bryopsida) inferred by morpho-anatomical and molecular analyses

Many bryophytes exhibit specific life forms that result in the formation of distinct patches. This is primarily achieved by "consequent vegetative multiplication" through indeterminate growth and vegetative reproduction. Little, however, is known about the underlying mechanisms and genetic patterns. In this study on vegetative multiplication in bryophytes, we apply morpho-anatomical and molecular (AFLP fingerprinting) techniques to analyze the vegetative reproduction system, clonal diversity, and habitat colonization of a pleurocarpous moss, Rhytidium rugosum (Rhytidiaceae). Morpho-anatomically, three types of vegetative diaspores are identified and illustrated: ramets, separated after decay and disintegration of older shoot parts (clonal reproduction); brood branches/branchlets; and caducous shoot apices (both vegetative reproduction s.str.). The AFLP fingerprinting of 35 samples (from two plots in Thuringia, further German populations, and from France, Russia, and Canada) resulted in the identification of three clones from the two plots, each comprising two to 15 samples with identical fingerprints. Samples from one clone occurred in both plots, thus proving dispersal of vegetative diaspores. The AFLP analysis further revealed close relationships of the plot samples, which suggest a clonal rather than generative (sexual) origin of the population.

Spatial clonal structure and patch colonisation in Ajuga reptans L. (Lamiaceae), a common stoloniferous semi‐rosette plant, were studied using a combined morpho‐ecological and molecular genetic approach. Within a natural patch from a forest near Diedorf (Thuringia, Germany), the spatial clonal structure was analysed, correlating both datasets: Morphologically, characteristics of clonal growth and clonal reproduction were studied, the spatial distribution of modules was mapped and merigenet relationships were reconstructed. Samples from the patch and its surroundings, and an additional sample from Berlin were then analysed by AFLP fingerprinting using four different primer combinations to identify genets. Most divergence in banding patterns was already obtained for samples from the Diedorf forest. Within the patch, however, most samples had very similar fingerprints, indicating their belonging to the same genet and hence a clonal origin, although they are morphologically separated into three “plants”. Based on AFLP data, the relationships of one sample remained ambiguous; but the correlation with morphological data helped to interpret the pattern and indicated that the sample is probably a dividual of the clone, too. The relevance of the observed vegetative multiplication (clonal growth and subsequent clonal reproduction) for patch colonisation and maintenance are discussed. (© 2005 WILEY‐VCH Verlag GmbH & Co.
